The Lowdown
Alright, let’s break this down in feet for the same stretch. We’re talking Costeño Beach – a consistent beginner-friendly break, open to the NE swell. Water temp is a balmy 84°F, which is spot on for the season.
First week is small and ordinary. From Monday August 31st through the start of September, you’re looking at waves around 3 to 4 ft from the NE, with short 7-second intervals. The energy is weak to moderate (89–174). You’ll get some glassy windows, but it’s mostly cross-on wind and a few afternoon thunderstorms. It’s a paddle, not a session.
The real moment comes on Tuesday September 8th. That morning, the swell jumps to 7 ft out of the NE with an 8-second period, and the combined energy hits 543. Wind is glassy, conditions are clean, and the forecast is for very good surf. That’s the standout – the single best session in the outlook. It’s big enough that beginners should sit it out, but for experienced surfers, Tuesday morning is the call.
Wednesday the 9th keeps it solid at 6 to 6 ft with glassy wind and good energy (279–323). Another strong day. From Thursday the 10th onward, the wind turns cross-on, bringing some chop. Swell stays in the 5 to 8 ft range through the weekend, with energy peaking at 725 on Thursday afternoon, but the bumpy conditions take the shine off. Still surfable, but not as clean.
By Sunday the 13th, the swell drops to 5 ft, and by Monday the 14th it’s down to 4 ft. Tuesday the 15th offers a bit of a rebound to 5 ft in the afternoon with a light cross-offshore, so the tail end might have a few clean ones again.
So, the first week is a waiting game. The clear winner is Tuesday September 8th – glassy head-high to slightly overhead NE swell. After that, there’s a solid Wednesday, but the second week turns wind-affected and smaller. If you want the best, show up on that Tuesday.

The above surf forecast table for Costeño Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Costeño Beach can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Costeño Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
